High-resolution image sensors with NIR+ for improved night vision

ON Semiconductor has introduced one of the first CMOS image sensors to feature its Near Infra-Red+ (NIR+) technology, which effectively combines HDR with enhanced low light performance to enable high-end security and surveillance cameras. The AR0522 is a 1”/2.5” 5.1MP image sensor based on a 2.2µm BSI pixel technology platform, developed for industrial applications that require high resolution, high-quality video capture in low light conditions. The AR0522 image sensor delivers approximately twice the sensitivity in the near Infra-Red wavelength of the existing AR0521 image sensor. The AR0431 is a 1/3.2-inch 4MP sensor based on a 2µm BSI pixel technology platform. Offering versatile low power modes and a frame rate of up to 120 fps, it is perfect for applications where slow-motion video capture is required. Its low operating power makes it ideal for battery-powered security cameras, as well as action/sports cameras, in-car DVRs and general surveillance cameras. Gianluca Colli, vice president and general manager, Consumer Solution Division of Image Sensor Group at ON Semiconductor said: “Our NIR+ technology and the back-side illuminated pixel platforms utilised in the AR0522 and AR0431 really come together to deliver outstanding image quality and low-light performance, resulting in brighter and sharper images even in challenging lighting conditions.”
